ERVIN W. HAYNES, OF FRANKLIN FALLS, NEV HAMPSHIRE.

DAMPER-REGULATQR.

SPECIFICATION forming part of Letters Patent No. 383,950, dated June 5, 1888.

Application filed November 152, 1887. Serial No. 255,004.

.hot-water or steam draft or damper regulators for steam boilers and heaters; and it consists 1n the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a perspective View of a heater provided with a draft or damper regulator embodying my improvements. Fig. 2 is a vertical sectional view of an upper portion of the same and illustrating my improved draft or damper regulating apparatus.

A represents a heater or furnace in t-he upper portion of which is a hot-water tank or chamber, B.

C represents an inlet-pipe to supply steam or hot water to the chamber B, and D represents a pipe to convey steam 0r hot Water from the said chamber. v The upper portion of t-he .chamber B is reduced in diameter and is provided with a central opening, E.

F represents an interior tank, which is arranged inthe tank or chamber B, and is provided at its upper end with the vertical pipe G, which extends through the opening E.

H represents a case, which is swiveled on the reduced upper portion of the chamber B, and is provided with a set-screw, I, by means of which it may be secured at any desired point. The said case H is provided with a cross bar or bridge, K, having a central opening, L, which aligns with the opening E. From one end of the cross bar or bridge extends a vertical standard, M, and from the opposite end ofthe same extends a vertical standard, N.

O represents a right-angular arm, which ex tends outward from the standard N and is then extended upward, as shown.

The upper end of the pipe G is secured in the opening L, as shown, and on the upper side of the cross bar or bridge K is a dia- (No model.)

phragm, P, which is made of rubber or other material and covers the upper end of tube Gr. The Said diaphragm is secured in position by a ring, R,r which is arranged on the same and is bolted to the bridge K by bolts R.

S represents an adjusting-nut, which is arranged above the center ofthe diaphragm and is provided with a threaded recess, as shown, and bears upon a follower, S.

I represents a lever, which is pivoted to the standard M, extends across and over the adj ustingnut, and projects through a vertical slot in the standard N.

U represents a screw, which has its upper end pivoted to the lever T and its llower threaded end engaged by the threaded recess in the nut S.

V represents a multiplying-lever, which is fulcrumed to the upper end of the standard O, is connected to the free endof the lever T by means of a link, XV, and is provided at one end with an adj listing-weight, X, which slides over a graduated scale, with which the lever V is provided, andv the opposite end of the said lever V is connected to a 'damper or draft reguulator, Y, with which the furnace is provided,

by means of a cord or chain, Z, as shown.

A branch pipe, A', communicates with the pipe G, near its upperend, and is provided with a. funnel, B', through which water and other fluids may be introduced through the inner tank, F, and has a stop-cock, C', as shown.

The operation of my invention is as follows: The inner tank, F, is entirely tillcd with water or other fluid, which rises to the upper end of the pipe Gr, and is heated by the hot water or steam in the tank or chamber B. Supposing that vit is desired to maintain the temperature of the water or steam in the radiatingpipes, (not shown) which are connected with the pipes attached to the outer tank, B, at 180, the Weight X will be moved to a point on the end of lever V indicating 180, and the adjusting-nut S will be turned, so as to cause the screw U to raise the lever T and the latter to lower the outer end of lever V sufficiently to j ust close the damper or draft regulator Y. In order to regulate the steam, the weight may be moved on the lever to the required point.

'When the pressure by expansion, caused by the' IOO temperature of' the water in the tank F, exceeds the pressure exerted by the weight X against the upper side of the diaphragm, the latter is pressed Aup against the follower, and the adjusting-nut consequently supporting the lever Tin its elevated position. When the water or fluid in the tank Fcools, it contracts and descends in the pipe G, thereby causing t-he diaphragm to lower, and consequently cans ing thelever T to be also lowered and the lever V to be raised sufficiently to open the door or regulator Y, when combustion in the furnace will be promoted snfciently to raise the water in the tanks to the requisite temperature, as before, when the draftregulator Y will again close.

By reason of having the case or frame H swiveled on the upper ends of the tank B, the same may be turned to any desired position on the heater, according to the side in which the draftregulator Y is arranged.

Having thus described my invention, I claim-- 1. The combination of the outer tank, B, the case or frame H, secured thereon, having the bridge K, the diaphragm P, and the follower on the said diaphragm, the inner tank, F, arranged in the tank B and having the pipe G, secured to the bridge K under the diaphragm, the levers connected to the said follower, the adjusting-weight on one of the said levers, the damper or door Y, and the connection between thesanie and the weighted lever, substantially as described.

2. The combination of the furnace having the door or damper Y and the tank B, the case or frame H on the upper side of said tank and adapted to turn thereon, said case or frame having the bridge K, the diaphragm resting on said bridge, thefollower ou said diaphragm, the levers supported on the case or frame, conH nections between the same and the follower and door or damper,rthe inner tank, F, arranged in the tank B, and the pipe G, extending upward from said inner tank and secured to the bridge K and communicating with the lower part ofthe diaphragm, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aXed my signature in V presence of two witnesses.
